SCALE.

To allwhmitmayconceriif- Be it known that LfJosnrn H ormNsoN, residingat Dayton, ltiontgomery county Ohio, have invented certain new anduseful Improvements in Scales, of which the following is a full, clear,and exactdcscription.

This invention relates to certain newand useful improvements incomputing scales of the typo shown in the patent to Hopkinson and Ozias,No. 867,671.v This improvement relates to an'iinproved lever system; toimrovements in the location of the main scalo cam; and to improvementsinthe connecting devices between the base lever system and the mainbenin a'iid indicating hand.

Tn. the drawings l-` igure 1 shows an-assembly view ofthe scale.

Fig. 2 shows a side -view oiV the baseaud the lever system therein.

Fig. 4 is a detail plan view o f the inter# mediate lever.

In Ii 1, 10 is the base of'the scale and 11 the c art housing connectedby a fraaie 12. Within the base `10 are a iuiinber of com ound levers1314. The arrangement of tiiese levers may lm .modilied in 'variousways` asi, will occur, to those skilled in the art. A platform.skeleton-15 is provided with'depcnding feet 16-which rest en knife,edges on the levers and thereby -supporti-he platforml 17.- One of thecompound levers as a portion 18 which extenddiagonally in the base(asshown in-["ig.'.l) and car-- ries on its cnda nose iron 19 having "adownwardly ointin'gflniife edge. A ink 20 is :provide with`a hookedort-ion'nt its lower ciidwhich engages the a o'resaidlfnife edge..'lfbejupper end ofthe .link is-liifur.l

maybe changed. The location of thebeams upon ythe top of the housing,however, is preferable in that it permits a customer atvth'eoppositeside of the scale to see the location of poise 27; In order thatthe custoiner may know theweieht -balanced by Patented Dee. 4, 1917.

the poise the op osite side of the upper beam is graduate f. This beammay be uttlizcd for taking ont tare or increasing the capacity of thescale.-

yAttached -to the end of the main scale beamby suitable knife edgemndloop connections is a shot cup stem 28 carryinga depending shot cup 29.This shot cup aids `m counterbalancing the weight of the base levers,platfornis,and connecting links and aids in maintaining the system in'equilibrium when there is noload upon the platform. 'Additional weights30 may be added tothe shot cup stein to increase the capacity of thescale. The shot cup steinis gradu' vated iis-shown so that the weightcounterbalanced by additional weights can be I quickly ascertained.

lhe eliart housing 11 carries a fan shaped computing chart 32 havingweightnnd price per weight graduations as 33 and 34. Arrangedto swingover the computing chart is an indicating hand 35 -.ivitlrprice pervpound markings thereon.v The indicating iandcari-ies the` usualindicating wire 36. The lower end -of the-indicating hand is attaehed toan eccentric cani 37. Thiseain is sup orteil-by knife edge pivots 3Swhich bear in block'benvingersl carried by braeketswhich 4extend.froinframe 12. The eccentric cain lias'securcd-to it a penduh'milWeight. 39 and also-has secured thereto al flexible tape 40 which-Lextends over the eccentric portion of tho cani and fhiwnwardly tofustirrup 41. The st irrup 41 connects the'liexible tape 40 with aninterniei'liate lever 42, which lever is ofthe lirst'ordei" of leverage.This intermediate lever' is'dis iosed parallel with and belowwtlie;chartand directlylbelow the eccentric cani ni id is provided with supportingknife ,edgeipivots 43 .which bear. on V block bearinf'sfasshown n-Fi'g.1.v The intermediate,` ever on the opposite side of the fulcram 'carriesan upwardl and'downwardly 1 pointing knife edge. gt4 w iichengages'upper and 1o\vei".L .V't blokjbearings '45 'and 46.Thesebeii'rings' are carried by link 20. The intermediate leverisweighted vat thecenter adjaeentthe fulcrum so that the knife edges4.3aiwaysremain in contact with their- V clearly shown in receivesstirrup 41 and the other bifurcation bearings. The oposite end isbifurcated as ig. 4. One bifurcation 47 48 bends around to rovide properclearance for the stirrup. Tli

e portion 48 oi.' the lever carries a threaded'stud 49. A counter,

weight 50 engages the treads -of this stud and isadapte to normallymaintainthe intermediate lever in the position shown. B

reason of the threaded studthe eounterba ancing effect of counterweght50 can be decreased or increased as desired. The stirrii 41 as shown inFig. 3 receives the bifurcate portion 4T of the intermediate lever'andis provided with a. spring pressed plunger 51 which bears'against thetop of ortion 47. The lower loop of the stirrup is t readed to receive abearing stud 52 which is conically cupped :it the upper end at 53- toreceive a conical bearing 54 which is carried by por-r, tion 47 of theintermediate lever.' One side' of the stirrup 41'is split and providedwith a lock screw 55. When it is desired to ad- 'ust the stirruconnection set screw 55is ooscned and t ereafter 52`is screwed up ordown. The plunger l at all times prevents the conical bearing 54 fromescaping from the cup 53. When the adjustment is completed, sot screw 55is tightened thus holding 52 in proper position. The spring pressed lunr 51 permits the disconnectionof t e stirrup and the intermediate leverwithout destroying the previous adjustments.

Operation.

When there is no load on the scale pendulum 89 is in elevated positionbein maintained in such position by t e weight of counterbalance 50.When a load is placed upon the platform tho compound levers in the baseof the' scaleare depressed thus lowering nose iron 19 and link 20.Bearing 45 presses against knife edge 44 and rocks intermediate lever 42-(a leveriof the"first.

order) counterclockwise, thereb elevating counterwei lit 50 and slackingo on flexible tape 40. he pendulum'39 then descends and swings th'eindicating hand 85 overthe chart to an extent -proportional to theweight on the pletfo i o I As previous? explained, if the wei ht on thescale plat orm exceeds t1ie .csp acity of the chart, the poise 27 andthe weights 80 may be emplo ed to increase the capacity. The dash potserves to reduce an .dampen lthe vibrations of the levers and aseociatedelements and cause the indicating hand to come uickly to rest. j
